APPLIUATION rum JAN. 2o, 1919.

UNITED sTATEs PATENT poiuuoE;l

To all whom 'it may concern:

Be it known that L'GEoRGE W. MORRIS;` a subject of the King of GreatBritain, residing at Racine, in the county of Racine, State oflViseonsin, have invented certain new and useful improvements inSpring-Mountings for Vehicles, of which the following is aspecification, reference being had to the accompanying drawings.

This invention relates to spring mountings for vehicles and has for itsobject to provide a construction by the use of which the rebound of thesprings upon which the bod of a vehicle is supported from the axles maybe controlled or prevented, said axles being mounted so as to swinghorizontally relative to the body as is necessary in turning a corner.The idea of providing means for controlling the rebound of thesupporting springs is disclosed and claimed in another application forpatent on spring mountings for vehicles filed by me of even dateherewith, Serial No. 539,149, and this feature is therefore not claimedby itself herein.

The means bywhich I have accomplished my object are shown in thedrawings and hereinafter specifically described.

riChat which I believe to be new is set forth in the claims.

In the drawings z-Figure 1 is a vertical cross-section through thecenter of one of my improved mounting devices, being taken on line 1-1of Fig. 2. Fig. 2 is a vertical cross-section on line 2 2 of Fig. 1.

Referring to the several figures of the drawings, in which correspondingpart-s are indicated by like reference characters :-1O indicates acylinder closed at its upper end by a perforated plate 11, having formedwith it, in the construction shown, an annular flange 12 to which at.opposite sides of the cylinder, there are secured by rivets or otherwisetwo short Iebeams 13 of sufficient height to extend some little distanceabove' Specification of Letters Patent.

Application led January 20, 1910.

Patented July 4, 1911. serial No. 539,150.

I above the other in the lower -end of the cylinder 16, provided ontheir adjacent faces with registering annular grooves.

20 indicates balls interposed between the two plates 18 19. l

21 indicates a coiled compression spring in the cylinders 10-16, bearingat its lower end against the plate 18 and at its upper end against theend-plate 11 ofthe cylinder 10.

22-23 indicate the members of a two-part two ears the ear 25 'is pivotedby a pin 27 passing through suitable openings in said ears. The pin 27is provided with' a suitable hole 2S through which a cot-ter-pin may bepassed to hold the pin 27 in place.'

29 indicates a bolt extendin upward through the perforated end-plate1g?, through suitable holes in the plates 18-19, and through theperforated end-plate 11 of the cylinder 10, the head of the bolt bearingagainst the under surface of the plate 17.

30 indicates a coiled compression spring mountedon the bolt 29 above thecylinder 10, the lower end of the spring bearing on" the upper surfaceof the plate 11 andthe upper end bearing against a cap 31 secured on thescrewfthreaded upper end of said bolt by nuts 32.

My improved device is especially designed for use in connection with thefront axle of a vehicle, but l do not limit myself' to that particularuse of the device, except as hereinafter claimed, as the invention maybe used in other ways wherever adaptable, whether or not the axle is tobe swungon a vertical pivot for turning corners. Indeed I do not wish tolimit myself to the use of my` device on a vehicle at all except asclaimed, as it may be used for supportin a body on any suitable base,between which body and base a partial or complete rotation is desired,said body being at the same time movable at right angles to t-hedirection of rotation and' held yieldingly against such movement.

`With a vehicle equipped with my improved device for connecting thefront axle to the lbody of the vehicle, the spring 21, will of courseserve to 'Support thev body, and the spring 3() may' be held stressedmore or less by adjusting the .nuts32-to, limit the rebound of thespring 21 as desired, the aXle being adapted to be swung on a verticalpivot in the ordinary manner without in any Way disarranging the springsor straining any of the mechanism, the anti-friction devices-enr ployedserving to prevent any tendency v'of the spring 21 to uncoil as oneAcylinder. is turned within the other.

`What I claim as my invention and desire to secure by Let-tersrPatentis,- y

l. The combination with a vehiclebody, a cylinder open at-its lower endsecured thereon, a hollow plunger open at'its upper end adapted to slideand to rotate freely in said cylinder, a coiled springinclosed withinsaid cylinder and plunger and'tending to pref vent movement of. saidKplunger into said cylinder, and anti'- friction devices interposedbetween one end of said sprin and its bearing whereby the rotation osaid plunger relative toV said cylinder may not cause said coiled springto unwind, of a link connected with said. plunger, a spring connectedwith said link and bearing on said cylinder and tending to preventmovement et said plunger out of said cylinder, and an axle connectedwith said plunger.

2. The combination with a vehicle body,

a cylinder open at its lower end secured thereon, ai hollow plunger openat its upper end adapted to slide and to rotate freely in said cylinder,a coiled compression spring inclosed Within said cylinder and plungerand bearing atA its upper end against the upper end of said cylinder,two superimposed plates having oppositely-disposed facing annulargrooves, and balls in said grooves, said latesbeing located in saidplunger with t e lower end of said spring bearing against the upper oneof said plates,

said spring tending to prevent movement of said plunger into saidcylinder, of a link connected with said plunger, a sprnig connected wlthsaid luik and bearing on said cylinder and tending to prevent movement`flanges to said beams, a hollow lunger open at its upper end adapted toslide and to rotate freely in said cylinder, and a spring inclosedwithin said cylinder and plunger and tending to prevent movement of saidbody and plunger toward each other, of a pin extending up throughsuitable openings in the ends of said cylinder and plunger, acompression spring mounted on said pin above said cylinder between saidbeams, means for holding said spring compressed on the upper portion ofsaid pin, and an axle carried by said plunger at its lower end.

e4. The combination with a vehicle body, a cylinder open at its lowerend secured thereon, a hollow plunger open at its upper end adapted toslide and to rotate freely in said cylinder, and a spring ,inclosedwithin said cylind er and lunger and tending to prevent movement oi saidbody and said plunger toward each other, of a link connected vwith saidplunger, a spring connected with said link and bearing on said cylinderand tending to prevent movement of said plun. ger out of said cylinder,an axle-box pivotally connected with saidplunger, and an axlecarried bysaid axle-box.
